Abstract
A system for determining the cross sectional profile of an object (24) having two opposed surfaces (26,28), includes: PA1 an ultrasonic transducer (16) having a reference surface (20) and arranged to emit and receive ultrasonic energy via the reference surface (20); PA1 a thickness determining unit (60) connected to the transducer (16) for causing the transducer (16) to emit ultrasonic energy via the reference surface (20) and for detecting reflected ultrasonic energy received by the transducer (16) via the reference surface (20) in order to derive indications of the distance between the reference surface (20) and an ultrasonic energy reflecting surface facing the reference surface (20); PA1 a carriage (2) supporting the transducer (16); PA1 a guide member (4) defining a linear travel path having a reference point and supporting the carriage (2) for movement along the travel path; PA1 a position determining unit (12,44,62) operatively associated with the carriage (2) for deriving an indication of the location of the carriage (2) along the travel path relative to the reference point; PA1 elements (32,34) for securing the guide member (4) to the object (24) so that the linear travel …
